As a DC comics only collector my entire POV is that the license should not be renewed when it's up. The Four Horsemen have been amazing but Mattel has simply never been a boys toy company when it's non-hot wheels and they show no sign of changing that now. Let Hasbro completely take over the toy world or put a proper business plan for dc collectibles in place.
IMO you need a little bit of perspective here. The DCUC line had gone thru 21 waves, with multiple other lines (Green Lantern Classics for example), two-packs, a 12-pack, etc.
What's going on with the line now is out of their control for the most part and even if Hasbro would take over things, they'd have to deal with DC just the same. But nonetheless, we're still getting figures.
The license also includes Imaginext, Hero World, Little People, Hot Wheels, etc. Not to mention the DC Unlimited & Batman Unlimited figures at retail.
A heck of a lot of DC product if you ask me.
